In a groundbreaking discovery, scientists have uncovered an expansive hidden landscape buried under the Antarctic ice. This vast terrain of hills and valleys, larger than the size of Belgium, has remained untouched for millions of years. With potentially over 34 million years of undisturbed existence, this hidden world is now threatened by human-driven global warming. The revelation sheds light on the mysterious and lesser-known land beneath the East Antarctic Ice Sheet, which is still largely unexplored.
Until now, the land beneath the Antarctic ice has been largely uncharted territory. Traditional methods of exploration, such as direct observations, proved challenging beyond the surface. However, utilizing existing satellite images of the ice’s surface, a team of British and American researchers managed to unearth this hidden landscape by tracing out the valleys and ridges that lie approximately two kilometers below. The undulating ice surface provided a “ghost image” hiding the spikier features beneath.
The resulting image presented a breathtaking river-carved landscape, complete with plunging valleys and sharply peaked hills reminiscent of topographies found on Earth’s surface. Comparable to looking out of an airplane window and seeing an intriguing mountainous region below, the researchers drew parallels to the Snowdonia area in Wales. This vast area of more than 32,000 square kilometers, once teeming with trees, forests, and possibly animals, was frozen in time when the ice took hold. The precise moment when daylight last graced this hidden expanse remains elusive, but researchers estimate it to be at least 14 million years ago, with some suggesting it could extend as far back as 34 million years ago when Antarctica first froze over.
While this discovery is of great scientific significance, it is also a stark reminder of the effects of global warming on our planet. The authors of the study highlight the potential threat that climate change poses to this newly discovered landscape. They warn that we are currently heading towards atmospheric conditions similar to those between 14 to 34 million years ago, when temperatures were three to seven degrees Celsius warmer than today. As global warming continues to accelerate, the pristine world beneath the Antarctic ice could be at risk of exposure.
It is essential to note that this hidden landscape sits hundreds of kilometers inland from the edge of the ice. Any possible exposure remains a long way off. Previous warming events, such as the Pliocene period three to 4.5 million years ago, did not expose the landscape, offering a glimmer of hope. However, the tipping point for a potential “runaway reaction” of melting remains uncertain. The study’s release coincided with another warning of the impending acceleration of melting in the neighboring West Antarctic Ice Sheet, even if global warming targets are met.
The discovery of this hidden landscape beneath the Antarctic ice not only sheds light on a mysterious and untouched world but also serves as a stark reminder of the impact of global warming. With the potential threat of exposure looming, preserving this frozen landscape is of utmost importance. Further research and monitoring are essential to ensure the preservation of this ancient landscape and to deepen our understanding of the Earth’s delicate and changing climate.
